Radcliffe was interviewed on Ryan Seacrest's On Air radio programme on Tuesday (January 31) and took the opportunity to assure Harry Potter fans that he gets on well with Grint.

"Rupert and I never text, we never have in 10 years of filming. We are crappy at texting each other back and we both know that's how the other person is and we just accept it," Radcliffe explained.

"The next time I see Rupert we will sit down next to each other and chat and it will be like old times. Me and Rupert are very, very good friends. It's just that we are not constantly texting each other."
